目的:对比分析腹腔镜直肠癌根治术应用脐上纵行辅助性切口与左下腹斜行辅助性切口的疗效。方法:回顾性分析厦门医学院附属第二医院2015年1月至2020年12月收治196例直肠癌患者资料，均实施腹腔镜直肠癌根治术。以采用不同腹部辅助性切口进行分组，对照组（101例）采用左下腹斜行辅助性切口，观察组（95例）采用脐上纵行辅助性切口。比较两组术中指标（手术时间、术中出血量、辅助切口长度、吻合口距齿状线距离）、术后指标（术后首次排气时间、术后疼痛评分、进流质时间、首次下床时间以及住院时间）以及手术并发症的差异。结果:观察组术后首次排气时间［（56.8±4.3）h与（70.3±5.8）h，n t=4.796］、术后首次下床时间［（38.81±2.04）h与（47.93±2.63）h，n t=5.113］均较对照组明显缩短，术后24 h的疼痛评分［（2.01±0.22）分与（2.43±0.40）分，n t=5.882］、48 h疼痛评分［（2.23±0.44）分与（3.14±0.72）分，n t=6.58］较对照组明显降低，两组比较差异均有统计学意义（均n P<0.05）。观察组切口疝发生率5.3%（5/95）较对照组9.9%（10/101）明显降低，差异有统计学意义（χn 2=4.29，n P<0.05）。n 结论:腹腔镜直肠癌根治术应用脐上纵行辅助性切口与左下腹斜行辅助性切口相比，不仅使患者术后疼痛评分显著降低、术后肠道功能尽早得以恢复，而且可显著降低术后切口疝的发生。“,”Objective:To compare and analyze the efficacy of supraumbilical longitudinal auxiliary incision and left lower abdominal oblique auxiliary incision during laparoscopic radical resection of rectal cancer.Methods:The data of 196 patients with rectal cancer treated in the Second Affiliated Hospital of Xiamen medical college from January 2015 to December 2020 were analyzed retrospectively. Different abdominal auxiliary incisions were used for grouping. The control group (101 cases) used the oblique auxiliary incision of the left lower abdomen, and the observation group (95 cases) used the longitudinal auxiliary incision of the upper umbilical cord. The intraoperative indicators (operative time, intraoperative blood loss, auxiliary incision length, distance between anastomotic teeth and dentate line), postoperative indicators (first postoperative exhaust time, postoperative pain score, fluid intake time, first out of bed time and hospital stay) and operative complications between the two groups were compared.Results:The first postoperative exhaust time ((56.8±4.3) h vs. (70.3±5.8) h, n t=4.796) and the first postoperative out of bed time ((38.81±2.04) h vs. (47.93±2.63) h, n t=5.113) in the observation group were significantly shorter than those in the control group, and the pain scores at 24 hours ((2.01±0.22) vs.(2.43±0.40), n t=5.882) and 48 hours pain score ((2.23±0.44) vs. (3.14±0.72), n t=6.58) after operation were significantly lower than those in the control group (all n P<0.05). The incidence of incision hernia in the observation group was significantly lower than that in the control group (5.3% (5/95) vs.9.9% (10/101), χn 2=4.29)(n P<0.05).n Conclusion:Compared with the left lower abdominal oblique auxiliary incision,the supraumbilical longitudinal auxiliary incision in laparoscopic radical resection of rectal cancer can not only significantly reduce the postoperative pain scores and recover the postoperative intestinal function as soon as possible, but also significantly reduce the incidence of postoperative incision hernia.
